MARLBORO, Mass., Nov. 4, 2004  /PRNewswire/ -- Raytheon Company (NYSE: RTN)
has been awarded a follow-on contract from NASA's Ames Research Center to
expand the Airspace Concepts Evaluation System (ACES).   The follow-on
contract is valued at $3 million for the base period of one year, with two
option years valued at $3 million each.

    The Raytheon team and NASA are committed to the enhancements of this
critically needed modeling capability that assesses the new technology air
traffic management tools to increase National Airspace System (NAS) capacity
and efficiency.  The enhancements to this simulation tool are an important
step toward establishing a methodology for successful development and
operation of complex simulations on a national scale.

    ACES is a NAS-wide framework of tools and models that is used to validate
advanced concepts that are being developed within NASA's VAMS (Virtual
Airspace Modeling and Simulation) project.  ACES is a comprehensive and
flexible modeling approach that allows for additional models to be added by
developers.  The ACES follow on contract will allow for further enhancement to
the infrastructure, increased models of higher fidelity, and additional tools
for use in the data management and analyses.

    "This sets the stage for NASA and Raytheon to continue developing advanced
tools and concepts for the future National Airspace System," said Bob Eckel,
vice president of Raytheon Air Traffic Management Systems.

    ACES was originally developed by Raytheon under the Air Traffic Management
System Development and Integration contract, with a team consisting of
Intelligent Automation Inc. of Rockville, Md.; Science Applications
International Corp. of Arlington, Va.; and Seagull Technology Inc. of
Campbell, Calif.

    Raytheon Company, with 2003 sales of $18.1 billion, is an industry leader
in defense and government electronics, space, information technology,
technical services, and business and special mission aircraft. With
headquarters in Waltham, Mass., Raytheon employs 78,000 people worldwide.
